# --description--

Dê a cada um dos elementos `th` um elemento `span` com a classe definida como `sr-only` e os seguintes textos, em ordem: `2019`, `2020` e `2021`.

# --hints--

Cada um dos elementos `th` deve ter um elemento `span`.

```js
const ths = [...document.querySelectorAll('table')?.[1]?.querySelectorAll('th')];
ths?.forEach(th => {
  assert(th?.children?.length === 1);
  assert(th?.children?.[0]?.localName === 'span');
});
```

Cada um dos novos elementos `span` deve ter o atributo `class` com o valor `sr-only`.

```js
const ths = [...document.querySelectorAll('table')?.[1]?.querySelectorAll('th')];
ths?.forEach(th => {
  assert(th?.children?.[0]?.classList?.contains('sr-only'));
});
```

O primeiro elemento `span` deve ter o texto `2019`.

```js
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('th')?.[0]?.children?.[0]?.textContent === '2019');
```

O segundo elemento `span` deve ter o texto `2020`.

```js
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('th')?.[1]?.children?.[0]?.textContent === '2020');
```

O terceiro elemento `span` deve ter o texto `2021`.

```js
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('th')?.[2]?.children?.[0]?.textContent === '2021');
```

O elemento `td` deve estar vazio.

```js
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('td')?.[0]?.textContent === '');
assert(document.querySelectorAll('table')?.[1]?.querySelectorAll('td')?.[0]?.children?.length === 0);
```
